Description:
Systematic interrogation of gene function requires the ability to perturb gene expression in a robust and generalizable manner. Here we describe structure-guided engineering of a CRISPR-Cas9 complex to mediate efficient transcriptional activation at endogenous genomic loci. We used these engineered Cas9 activation complexes to investigate single-guide RNA (sgRNA) targeting rules for effective transcriptional activation, to demonstrate multiplexed activation of ten genes simultaneously, and to upregulate long intergenic non-coding RNA (lincRNA) transcripts. We also synthesized a library consisting of 70,290 guides targeting all human RefSeq coding isoforms to screen for genes that, upon activation, confer resistance to a BRAF inhibitor. The top hits included genes previously shown to be able to confer resistance, and novel candidates were validated using individual sgRNA and complementary DNA overexpression. A gene expression signature based on the top screening hits correlated with markers of BRAF inhibitor resistance in cell lines and patient-derived samples. These results collectively demonstrate the potential of Cas9-based activators as a powerful genetic perturbation technology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4420636/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4420636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Konermann, Silvana -- Brigham, Mark D -- Trevino, Alexandro E -- Joung, Julia -- Abudayyeh, Omar O -- Barcena, Clea -- Hsu, Patrick D -- Habib, Naomi -- Gootenberg, Jonathan S -- Nishimasu, Hiroshi -- Nureki, Osamu -- Zhang, Feng -- DP1 MH100706/MH/NIMH NIH HHS/ -- DP1-MH100706/DP/NCCDPHP CDC HHS/ -- R01 NS062849/NS/NINDS NIH HHS/ -- R01 NS073124/NS/NINDS NIH HHS/ -- R01-NS07312401/NS/NINDS NIH HHS/ -- England -- Nature. 2015 Jan 29;517(7536):583-8. doi: 10.1038/nature14136.
